Application filed September 3, 1919. Serial No. 321,430.

To all whom it may concern.'

Be it known that I, .loi-1N S. E. PANiisE- virer-I, a citizen of the United States, resid ing at Northampton, in the county of Hampshire and State of Massachusetts, have invented a new and useful Gas Heater and Cooker, of which the following is a speciiication.

This invention has reference to gas heaters and cookers, and its object is to provide a simple and efficient construction for the purpose, which may be inexpensively manufactured and is portable.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding, howeverj that the invention is not confined with any strict conformity to the showing of the drawings, but may be changed and modified so long as such changes and modiiications mark no material departure from the salient features of the invention as expressed in the appended claims.

ln the drawings:

Figure 1 is a side elevation of the gas stove.

Fig. 2 is a vertical diametrical section, with some parts in' elevation, and with the top of the stove swung to one side.

Fig. 3 is a vertical diametrical section of the inner cylinder of the stove.

Fig. 4 is a planA view of shown in Fig. 3.

Fig.` Fig. 3. Y

Fig. 6 is a section on the line 6 6 of Fig. 3.

Fig. 7 is a vertical diametrical section of the inner cylinder on a different plane from that of Fig. 3.

Fig. 8 is a plan view of one of the partitions, illustrating the manner of fastening the partition to the shell of the cylinder.

Referring to the drawings, there is shown, in Figs. 1 and 2, a casing 1 which may be of the usual cylindrical form, common to portable gas heaters, but is not necessarily limited to such particular shape. The casing 1 is mounted on a base 2 in the form of an annulus, like gas stoves in general, and feet 3 are provided for sustaining the base 2 in an the structure 5 is a section on the line 5-5 of elevated position. For the purposes of rigidity and stability the feet 3 are held to the base 2 by bolts 4. Furthermore the base 2 carries a bottom plate 5 held to the base by bolts 6 and provided with numerous perforations 7 whereby air from the atmosphere finds ready passage into the interior of the casing 1. The top of the casing 1 carries a crown ring 8 provided with an opening surrounded by a ledge 9 for the reception of a removable lid l0. The crown ring 8 is arranged to carry a cap or dome 11 `such as is customarily provided in gas stoves, and this may be made of ornamental configuration to enhance the appearance of the stove. Also the casing 1 has top and bottom series 12 and 13 of perforations for the 'entrance of air into the casing at the lower end and the esctpe of air from the casing at the upper enc.

Nithin the casing 1 there is lodged a drum or cylinder 14 having its upright walls provided with series 15, 16, 17 and 18 of perforations, such perforations being prefer-v ably of like size and extending circumferentially of the drum 14. At the lower end the drum is formed with legs 19 spaced apart, some of the legs having extensions 2()V passed through suitable perforations in the bottom plate 5 and anchored to said bottom plate by pins 21 traversing the legs, or in any other suitable manner, preventing accidental displacement of the drum.

At different levels in the drum there are located plates 22, 23 and 2li, and the drum has a cover plate 25. The plates 22 and 23 are each provided with a central passage 26 with jointed strips 27"t1aversing and dividing the passage 26 into a circular series of separate passages, each plate 22 and 23 having in the particular construction shown7 three strips 27 and three passages 26, the plates being so arranged that the passages and strips of one plate alternate with those of the other in the direction of the height of the stove as seen in Fig. 5. The plate 24. (Fig. 6) is formed with a central passage 28 with a surrounding series of perforations 29 between the central passage 28 and the outer margin of the plate.

The plate 25 (Fig. 4i) which constitutes the top of the drum 14- is formed with numerous perforations 30 constituting the only passages through the plate and so arranged as to include the entire area of the plate.

Each of the plates 22 to 25 is provided with marginal tongues 3l shown in Figs. 2, 3, 4 and 8, which tongues are extended through perforations 32'in' the upright wallof the drum 14 and are appropriately bent to fasten the plates in place and at the same time support these plates. e lVihin the casingrl, at a short distance above the plate 5, are brackets 33 projecting towardxthe longitudinalV section line of the casing and designed to support a Vburner 34 having a pipe 35, which may be of the Bunsen type, extendingv to the exterior of the casing and lthere connected to a gas supply pipe 36 and including a controlling valve 37. Through one side of the casing l adjacent to the burner 34 is a passage 38 or' such size than the neXt higher plate 23, and so to the as to readily admit a-lighted match, and suliciently close tothe burner so that with th gas turned on the Vgas jetsrissuing from the burner maybel lighted from the exterior of the drum I4, the hole 38 being close to one'ot-the passages between the legs 19 of the drum. v

While the Vdrum 14 is indicated as being made of sheet material, such as sheet metal, it is to be understood that it may also be made of tire brick, the two structures differingA in material and to Van extent in operation Yin tha-t'the fire brick takes longer to heat and will retain heat longer than sheet metal, butotherwise it is immaterial Whether fire brick or sheet metal be employed, except that in the case of tire brick Athe Weight'oif' the stove as a Whole is'greater than when sheet metal is used; Y

The first plate over the burner, namely, thevplate vE24, is made of heavier gage ine al top plate. This is because Athe plate 24 is subjected to more intense heat than the succeeding plates'higher up'. e 'l The stove is readily adaptable, withy gas as the heating agent, for either orboth heating and cooking, no unpleasant odors occur-V rinor While the arrangement of the lates C? f3 Y l Vand perforations VinV the drum or mantle Vcauses perfect combustion and etliclentradi- Y nature.

ation of heat throughout all parts of the stove.

lVhat is claimed is:

l. A gas stove comprising a heat radiating casing, a drum Within the casing spaced 5 from the side Walls thereof, saidl-` drum having superposed series of circiunferentially arranged passages through its upright Wall, and division plates or partitions in superposed order Within the drum,4 With Yeach 6 plate car 1ied by. the. drum immediately belou7 a corresponding circumferentially arranged series of passages, the loWermost plate or partition having a central passage through it with surrounding perfora- 6 tions, the higher plates having passages through them smaller than the central paspsage through the lowermost plate and in staggered relation, Vand the ytop of the vdrum being provided with numerous small passages or perforations therethrough, the plate nearest. the heating element being of heavier gage than the Aplatev above the same and lso on up to the top plate. Y

2. A gas stove comprisinga heat radiat- 7 ing casing, a drum Within'the casingV spaced" from the Vside Walls thereof, said drum having superposed series or' 'circumferentiallyv arranged passages through' its upright SWall, and division plates or` partitions in vsupers d posed 'order VWithin the Vdrum, With .each

tongu'esto support and anchor the platesv in 9 place in the drum. e i

In testimony, lthat I claim the foregoing as my own, I havel hereto aliixed ,sig-
